HDR done in software.

The camera can also help the camera will shoot 3x (normal, under & over) exposure.
Then the image files to 3 tsb done HDR technique (can be done in photoshop / camera).
Terms HDR, when cameras would shoot 3x, not in the camera changed angles, zoom, settings, etc..
Use a Tripod as a maid.

Choosing a DSLR camera, do not care about his ability HDR (HDR ga essentials within the camera)
Like buying a car, you focus on the car radio, you forgot tp attention on his engine.
HDR function on the camera is just a sweetener.
HDR done in the computer, with more satisfactory results.

focus motors "built-in body", you mean, auto-focus motors inside that body?
This of course is more expensive camera and focus motors "built-in body" is more important than the no "built-in body"

With "built-in body" lens you can use the old model (which is cheaper and quality) and can autofocus.
dr pd without the "built-in body" you have to buy lenses that new models (more expensive and the quality is the same with the old model).

The hell with HDR, important notice any kind of lens models which will compatible with your camera later.
Eg Nikon D3000 and D90.
D3000 (without motors "built-in body") would have to buy a new lens AF-S models (expensive)
D90 (motor built in body) could certainly use AF lenses (cheap) and AF-S (expensive).

Note: not all cheap AF lens and AF-S expensive. See the first class.
 
Parables, such as this, an Olympic gold medal winning athlete, then a few moments later the medal was revoked because he was caught breaking the rules. Herry photographer Fisch experienced something similar to this when he declared the first prize in the National Geographic photo komtes place to categories and traveling, but in the next 72 hours his title later in disqualification.

Cause Herry disqualified? Herry using the cloning tool in Photoshop to eliminate plastic waste which is on the right side of the picture. See the two photos below, the above is the original image while the photo below is a photo with the cloning tool.
Contest rules specifically mention that the photo processing is permitted only burning (darken) and dodging (make brighter), while eliminating certain object is expressly prohibited.

Actually there are two scenarios that can be done to eliminate the waste Herry without breaking the rules of the contest:

    1. Using crop to crop the image so that the garbage is taken truncated
    2. Doing so burning garbage to be not visible and not using cloning.

In an email to Herry, editor of National Geographic clearly said, "Unfortunately you do not crop the trash, or even let it, because it really does not give effect to waste anything."

Rice has become porridge. A clear lesson to keep in mind is, read and know the rules and obey a photo contest, photo contest, especially if you follow such a prestigious enough.
 
What Is a Neutral Density Filter?

Filter Neutral Density (ND) is the main filter for long exposure photograph. ND filters are no different from the physical shape and the polarization filter mounted in front of the screw through the lens, see pics below. ND stands for Neutral Density, Neutral words or less because it does not change the direction and character of the light. While the density because it reduces the intensity of light. So more or less could be interpreted as a useful filter to reduce the intensity of light but does not change its character.

With a wide range of digital cameras on the market today, the initial question that no head of any photographer is "Which camera should I buy?". The answer to that question usually depends on the funds available and the type of photography you want occupied.
In general there are three types of cameras on the market, namely: the camera point-and-shoot (often referred to as a pocket camera / pocket), prosumer cameras (compact cameras), and a DSLR (digital single lens reflex). The main difference between the two types of cameras that first mentioned the DSLR camera is the lens system. DSLR camera lens can be replaced as needed while the camera lens point-and-shoot and compact cameras can not be replaced alias permanently mounted on the camera body.


 
Crop factor is a term that is quite often heard in the world of digital photography. Crop factor closely related to the ratio of the size of the resulting image compared to the size of the reference, in this case the reference in question is the size of 35mm film (the size of the image in the film is 36 x 24mm). Mathematically, the crop factor is the ratio between the diagonal of 35mm film (43.3mm) diagonal image with a digital camera sensor.

Crop Factor (CF) = Diagonal 35mm / Diagonal image sensor

 
 
 
 
In this article, we will try to understand what a pixel, and the resolution megapixel digital photos. And if megapixels are important factors in deciding which camera should you buy?
Pixels and Megapixels

A digital picture is made up of millions of tiny dots called pixels (pixel). Pixel itself is a word derived from the abbreviation Picture Elements. Each pixel carries information that determines the color (hue), the strength of the color (saturation) and how bright the colors are displayed (brightness).
